Was it a 979 Vitus ? I had the same problem but where the seat tube connects to the bottom bracket. I was told it was because I was too heavy (fat) for the frame.
I have found a guy who does repairs on these things but he is in Vancouver Canada . I think the cost of the service is reasonable, shipping the frame over and back probably isn't. http://www.guywires.com/vitusmain.htm
